1 Claim.

I'his invention relates to combustion promoting devices for internal combustion engines, and has more particular reference to certain new and useful improvements in the device disclosed in 5 the U. S. Patent to A. P. Sollender No. 1,324,281

granted December 9, 1919.

The primary object of the present invention is to generally simplify and improve the device of the above-mentioned'pat'ent.

l0 Another more specific object of the present invention is to provide manually operable means for regulating the maximum amount of air admissible through the air inlet openings of the fitting which is interposed in the conduit that connects the water circulatingsystem of the engine with the intake manifold of the latter.

Still another object of t'he present invention is to provide such an air admission controlling or regulating means which is simple in construction, eflicient, and constructed to effectively maintain the adjustments thereof. Y

Other objects will appear as the nature of the invention is better understood, and the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing: Figure 1 is a view showing the present device in elevation and partly broken away.

Figure 2 is a view similar to Figure 1 with parts broken away and in section. Figure 3 is a section on line 3 3 of Figure 2. Figure 4 is a section on line 4-4 of Figure and Figure 5 is a fragmentary elevational view showing a modified form of fitting constructed in accordance with the present invention.

Referring in detail to the drawing, a fragment of the intake manifold of an internal combus- 40 tion engine is indicated in Figures 1 and 2 at 5,

while a fragment of the water circulating system of the engine is indicated at 6. The present device includes an elbow I for insertion in the intake manifold 5, a fitting including a tubular casing 8 in which a valve 9 is yieldingly held seated by a spring I0.

As in the above-mentioned patent, the valve 9 is preferably conical and closes both of two spaced ports II and I2, by the resilient effect of the spring Ill. Also, as generally shown in said patent, one or more openings I3, open to the atmosphere, are provided in the casing 8, between the ports II and I2 for the admission of air. The usual conduit I4 is provided for conadjustable on the casing 8 for regulating the denecting the tting with the part 6 of the water circulating system, the latter being facilitated by means of a suitable end connection member I5 on one end of the conduit I4. A valve I6 that may be suitably controlled from the in- 5 strument board of an automobile, is provided for controlling the flow of water or moisture through the conduit I4 to the manifold 5. However, instead of providing this valve on the end of the conduit I4 which connects with the part 6 of the 10 water circulating system, it is arranged at and coupled to the other end of the conduit I4 adjacent the casing 8, as at I1. The casing 8 is formed integral with the other end of valve I6, thus providinga single fitting embodying both 15 the valve I6 which is manually operable and the valve 9 with its associated parts. One end of the elbow 'I is adjustably threaded into the outer end of casing 8 for varying the strength of the spring I0, the adjusted relation of the 2O elbiowa'l and the casing 8 being secured by a'lock nu While not shown herein, it is to be understood that the intermediate portion of the conduit I4 is to be wound around the exhaust pipe of the 25 engine or` otherwise suitably heated.

-In accordance with the present invention, the air inlet openings I3 are in the form of longitudinal elongated slots in the casing 8, and a sleeve valve I9 is provided and longitudinally 30 gree of opening of the slots I3 and thereby regulating or controlling the maximum amount of air admissible through said slots I3. Suitable means is provided for preventing accidental longitudinal shifting of the sleeve valve I9 relative to the casing 8 so that it will remain in any of its adjusted positions until manually adjusted. Obviously, it is important to make this provision in a device placed upon an automobile and subject to being disturbed by vibration or otherwise. A most efficient construction is had by threading an end portion of the valve I9 on the outer end portion of the casing 8, the inner end portion of the casing 8 being provided with a smooth cylindrical external surface engaging a corresponding internal surface in the inner end portion of the sleeve valve I9 as shown more clearly in Figure 2. However, even a threaded adjustment is such as to allow accidental turning and consequent longitudinal shifting of the sleeve valve I9 under certain conditions, and for this reason additional means is preferably provided for resisting accidental rotation of the valve I9. As shown in Figures 1 to 4 inclusive, this means may consist of a suitably shaped spring band 20 disposed in an annular external groove 2I provided in the outer surfaceof the smooth inner end portion of the casing 8 and having spaced portions alternately contacting the surface of the casing 8 at the bottom of such groove and the inner surface of the adjacent end portion of valve I9. By properly regulating the rigidity of the spring 20, it may oiTer the desired frictional resistance to turning of valve I9, as will be apparent.

However, as shown in Figure 5, the means for preventing accidental turning of valve I9 may take other forms. In Figure 5, this means consists of a spring tongue 22 struck from the inner end portion of the valve I9a and adapted to engage in any one of the slots or openings I3 when alined therewith. The arrangement is such that the tongue 22 may be forcibly moved out of the slot by manual turning of the valve I9a with appreciable force, the inner surface of the tongue 22 being slightly rounded or beveled to avoid a positive lock. Otherwise, the device of Figure 5 corresponds to that of Figures 1 to 4 inclusive, and will be similarly used with the other parts of Figures 1 and 2 in a complete device.

The present invention operates in exactly the same way as the device of the patent mentioned above, except that the valve I6 is diierently positioned and the valve I9 is provided to regulate the maximum amount of air admissible through the air inlet openings I 3. It will be seen that a more definite proportion of air and moisture will be had by the present improvement, while the re-arrangement of parts provides for more ready manufacture and simplification of the construction as disclosed in said patent. Minor changes may be made without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

In a combustion promoting device of the character described, the combination of a tting having an opening extending axially therethrough and a pair of spaced internal valve seats and longitudinally elongated openings leading to the atmosphere and opening into said axial opening between said spaced valve seats, a pipe member threaded into one end of said fitting, a reciprocable valve tting both seats, a spring interped between said pipe member and said valve for normally holding said valve on said seats, and a manually operable sleeve valve having its upper portion threaded on the outside of said fitting for adjustment longitudinally of the latter to regulate the amount of air admissible through said elongated openings, the lower portion of said sleeve valve being snugly fitted about said tting
